Assume that you instead invest the money ($15000) at an annual rate r, then after 2 years this must be worth$20000 to be an equivalent investment, and r is the annual rate of return on the investment.

3. ## Can you..

Can you break it down another way?

$100 \times$ $$20 =$$ $2000$

So, over two years, she has had a profit as the stocks are worth more than she paid so she has earnt:

$$2000 -$$ $1500 =$ $$500$ So, per annum ( $1$ year) this would be:$ $500 \div 2 = ...$
An annual interest rate will result in compounding annualy so you will not earn the same interest in each year.
